How to change car rims colour?

I remember back in the days that I could change the rim colours from the T3D editor but I can't find that option right now. Can you guys help?

 

Just find the rim file through material editor and select color i think . If you don't get it , i'll give you an illustration

 

That's the problem, I can't file the file through the material editor.

 

Ok . So for example , i want to change the Sunburst's rally rim color from white to dark grey .

I select the whole car , but extra stuff will appear .

That's why i select only ThePlayer from the list of Objects .

I go to material editor and there you go . I don't know if all cars have the same filename so i'll just choose wheel-05a .

I choose layer 1 and i just click the box with white color and a menu should appear . The textures may not work properly so i choose 2 as the Alpha value . ( Matte )

Voila . Now the car's color . Blue just doesn't match .

There . Enjoy your new shoes .

 

Thanks a bunch but when I exit the editor the rims revert to their stock colour.

 

Oh yeah , just press Alt-s .
or just click the save button .

 

Yea, figured that out. Thanks!
